The development of two types of X-ray microscopy applying to the organic objects investigation (biological samples and polymer matrix) is reported. Polymer track membranes were investigated using Schwarzchild X-ray microscope with 20 nm wavelength. Pore diameters down to 0.2 Î¼m were clearly imaged. Contact X-ray microscopy at 0.229 nm wavelength was used to obtain clear images of inner structure of native biological samples. High contrast together with the high resolution (about 2-3Î¼m) allowed us to use this method for quantitative analysis of demineralization process taking place in the skeleton of amphibious after several weeks of weightlessness on biosputnik board.

Intracellular mapping of elements was performed for Cd or Hg loaded mammalian cells. X-ray contact microscopy with an electronic zooming tube were used for cell imaging at the resolution of 0.5 Î¼m. The mapping was obtained by the subtraction between images taken at two different wavelengths....

Soft X-ray microscopy employs the natural absorption contrast between water and protein in the 2.34 - 4.38 nm wavelength region with a resolution down to 30 nm. The large depth of focus of the Fresnel zone plates used as X-ray objectives permits tomographic reconstruction based on the...

Soft x-ray microscopy is now routinely capable of imaging biological specimens with resolutions that are five times better than the best visible light microscopes (â‰¤ 50 nm). However, for biological labeling the only options developed for x-ray microscopy have been silver enhanced gold...

Platelets are anuclear discoid-shaped blood cells with key roles in human body. To understand the mechanisms of their activation process, it is required to have analytical imaging techniques capable of acquiring platelet images under fully hydrated conditions. Herein, for the first time, we...

A first X-ray imaging microscopy test using the two types of â€œmicro-capillary lensâ€ (kind of the X-ray refractive lenses) has been done at the undulator and bending magnet radiation of SPring-8. One (lens No.1) contained bubbles in glue whereas the other (lens No.2) contained bubbles...

By using high technology an X-ray microtomograph (micro-CT) was created as a simply usable, desktop instrument. The micro-CT is a laboratory system for non-destructive three-dimensional microscopy, giving true spatial resolution over a million times more detailed than the medical CT-scanners.

At the ESRF micro-fluorescence, imaging and diffraction (Î¼-FID) beamline ID 22, a microimaging and tomography setup has been operational for several months. The coherence properties of the high-energy X-ray undulator beam at ID 22 make the setup especially suited for phase-contrast tomography...

X-ray microscopy and scattering experiments give different experimental results when determining the fractal dimension of colloidal clusters. A two dimensional simulation model is presented to describe reorganization of clusters during the aggregation process. Considering this reorganization...
